Welcome to YuneecPilots.com!

Several people including myself have been seeing issues when connecting the ST16 HDMI port out to an external HD field monitor.Of the 2 professional field HD monitors I own,only one would sync with the video feed from the ST16.

Even when working,the video image on the ST16 would go blank yet the video image would still show on the external HD monitor.Tapping the ST16 screen twice would bring the screen back up,but it would once again go blank after a few seconds.

As this is happening to multiple users,I think this is a hardware/software conflict issue with the ST16 and 3RD party external HD monitors.I just want anyone reading this to understand that if you plug in an external HD device into your ST16 it may or may not work.

This is rather concerning as the ST16 HDMI out port is a major reason many have purchased the H.I believe Yuneec needs to address this issue asap.

So, I ran this test just now. ST16 with silver switches, I haven't done any firmware updates. The secondary monitor will connect to the ST16 and display and stay on. It will also stay on in Pad mode. However, in Flight Mode, if I double click to display the video feed full screen, the ST16 monitor turns off in 5 seconds, but the secondary monitor always has a video feed. Touching the ST16 screen turns the ST16 screen back on, but again for only 5 seconds.

I'm sure this is something Yuneec can fix in a future firmware update.

I'm another that has experienced this problem with the chrome switch ST-16. When I made the decision to purchase the H, having HDMI out was, and still is, a large part of my reason for buying it. When I build a camera rig, always a hex or greater, one of the features I install on them is HDMI out, with another a 360* gimbal. Not having functional HDMI out significantly reduces the benefits that were advertised as part of the Typhoon H imagery features. The H flies nice but lots of multirotors do that.

Sorry to hear you too are having an issue. This is beginning to looks like it affects all ST16 conrollers.

Have a functioning HD signal out to ALL HD monitors was very much a major reason in buying the H. As it stands now,the HDMI out is all but useless.

My ST16 seems a bit different. It's a Chrome Switch Model and I use the HDMI connection with Headplay HD FPV Goggles. With the Headplay Goggles connected, the ST16 flight screen stays Active. If I switch to PAD and play a Video, the ST16 Screen switches off..........Just tried this with a Monitor - The same.

When you say the ST16 flight screen stays active,do you mean the video image and telemetry overlay are both present on the ST16 screen and Headplay? If so, double tap the ST16 screen to just view the cameras feed without telemetry/controll overlay. When you do that does the ST16 screen go blank?

'YES' to your first Question..........'NO' to your second Question.........The only time the ST16 screen goes Blank (with HDMI connected) is in PAD Mode.

Do notunder any circumstances switch to tablet mode while the H is in flight. I have already done this and link with the aircraft is immediately cut. The aircraft goes into RTH mode and comes to a point at the Safe Circle distance and hovers.

Hello,
i confirm you the same problem. Out HDMI no works with secondary monitor. It is anormal.
idem PatR
"When I made the decision to purchase the H, having HDMI out was, and still is, a large part of my reason for buying it."
